Background Research
Have you ever wondered how you stop and start on a hill in a car? This is why I did my project. When I did my project, I discovered that my project is based on friction, height and the stopping point of a car.Traction, the friction between a tire and the ground, is essential for a vehicle to perform well in less than perfect conditions, such as on slippery slopes. Proper traction is just as important for toy vehicles as it is for full-sized automobiles. Friction is based on my project because rolling the car down the ramp on to the treatment is causing friction.
The ramp that I used was made of house hold items.I used a box and another piece of cardboard.The definition of height is distance upward from a given level to a fixed point. This applies because for all of the treatments I used the same height for the ramp.
When a car stops it also has to deal with friction. But more specifically friction between the brakes and the wheels and friction between the tires and the road. Friction is what happens when the car stops on the surface. What makes a toy car stop is not just friction it is also gravity. When the car came down the ramp it had gravity pushing it down but, when it was on the flat surface it stopped because of friction.
My is based on friction, height, and the stopping point on a car.These all are involved with my project because the height of the ramp, the friction of the the car tires and the different surfaces, and why the car stopped were it did.

Conclusion
My hypothesis was right because the rocks had the shortest distance recorded and ice was "off the charts".Discussion
My data showed that the slippery treatment (ice) has the less friction with the car. I was able to answer my question accurately by doing this experiment.Benefit to Community and/or Science
My data can be used to help manufacturers make tires more efficiently.Abstract
My project is deciphering what surface will stop a car the fastest. My hypothesis was that the rocks will stop it fastest. I will use rocks, ice, dirt, and mud. I will use house hold items to do my project so that I will not create any environmental concerns. I will roll a car down a ramp on to the different surfaces. Then I will measure how far the goes on the surface for my data collection.My results show that my hypothesis was right, that the rocks do stop the car the fastest.
